Nash explains that web applications intended to improve the public input process for transportation projects often come up short:

The simplest example is using websites and e-mail to comment on planning studies. [But] often these systems are not very creative, simply mimicking the traditional paper-based planning process, which shows that there is room for innovation. An interesting idea is CitiWiki Pittsburgh’s project for creating a regional integrated transportation plan... It was meant to provide those who have a vested interest in creating a better transportation system with a tool and a venue for sharing their ideas for productively building such a system.

...allows users to examine the impacts of public transport improvements on their own public transport routes. The game will both teach users about public transport operations and help them assess the value of their ideas... For example, the player could add traffic signal priority by dragging the “public transport priority signalization widget” onto the route map at the intersection.
